How much gold did the Spanish galleons take from the New World?

A lot of. Only one of them, "Santa Margarita", which sank in 1596 off the coast of Florida, took to the bottom of gold worth more than 8 million dollars.

 Random interesting fact from the Great Encyclopedia:

How did Perseus manage to kill Medusa, who can turn a person into stone with just a glance, and what did he need for this?

Perseus was the son of the Argive princess Danae and Zeus. By the will of fate, Perseus and Danae ended up on the island of Serif, where Perseus grew up in the house of the local king Polydekt.

The time has come when the already matured Perseus had to protect his beautiful mother from Polydectes, who tried to marry her against her will. To get rid of Perseus, Polydect sent him after the head of the Gorgon Medusa - a terrible, scaly winged monster with burning eyes, huge fangs and snakes instead of hair, one look of Medusa was enough to turn a man into stone.

Perseus came to the aid of Athena, who hated Medusa, in whose terrifying appearance she was to blame. First, the goddess took Perseus to the island of Samos, where the statues of all three gorgons stood, so that Perseus could distinguish Medusa from her immortal elder sisters Stheno and Euryale. Then she warned Perseus not to look at Medusa herself, but only at her reflection, for which she presented him with a shield polished to a shine. He helped Perseus and Hermes by handing him an adamant curved knife with which to cut off the head of Medusa.

However, Perseus still needed winged sandals, a magic bag in which to store a severed head, and a cap of invisibility that belonged to Hades. All these things were kept by the Stygian nymphs, whose whereabouts were known only to the sisters of the Gorgons - swan-like grays, who had only one eye and one tooth for three. Perseus began by seeking out the Grays, who sat on thrones at the foot of the mountains to the west. Creeping up behind them, he snatched out an eye and a tooth as one of the sisters handed them to the other, and agreed to return the stolen item as soon as they told where the Stygian nymphs lived. When the Grai reluctantly gave him the required information, Perseus threw his eye into Lake Triton so that they could not warn their Gorgon sisters of his arrival.

Having easily taken sandals, a bag and a hat from the nymphs, Perseus flew west, to the land of the Hyperboreans, where among the statues of people and animals petrified by the gaze of Medusa, he found sleeping gorgons. Staying away from the immortal Stheno and Euryale, Perseus crept up to their younger sister, watching her reflection in the shield, and with one wave of his hand, guided by Athena, cut off the head of Medusa with a knife.

To his surprise, the winged horse Pegasus and the warrior Chrysaor emerged from her dead body. Perseus quickly put Medusa's head in a bag and rushed to run. Stheno and Euryale, awakened by their newly-born nephews, rushed after Perseus in pursuit, but he, putting on an invisibility cap, safely disappeared.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Conductive protein for 3D microarray assembly 13.02.2013

Three-dimensional microchips are considered the ideological heirs of modern "flat" microchips. It is believed that such devices will become more compact than their predecessors, and will have greater performance and less heat. The production of such devices has not yet been established due to the high cost of such chips and technological difficulties, as a result of which the percentage of yield of suitable crystals remains extremely low.

Manuel Thery from the University of Grenoble (France) and his colleagues have developed a cheap alternative to modern methods of assembling three-dimensional microchips, having learned how to manage the assembly of "biowires" from protein molecules. Scientists drew attention to the protein actin, the molecules of which form the "skeleton" of all cells in the human body. It is a water-soluble short chain of four hundred amino acids. When magnesium ions appear in solution, actin fragments quickly connect to each other, turning into strong polymer filaments.

Teri and his colleagues learned how to grow these filaments in the right parts of the “halves” of a three-dimensional chip by attaching special “seed” molecules to silicon wafers that caused the actin filaments to turn into a polymer without magnesium ions. These threads are intertwined with each other with a fairly small distance between the parts of the chip, forming strong "tunnels", the walls of which conduct current due to the gold atoms attached to them.

According to biotechnologists, this design conducts current no worse than "classic" metal contacts between layers of 3D chips. The low cost of protein molecules, the relative ease of their fabrication, and compatibility with other silicon microchip "growing" techniques make this technology a serious competitor for current XNUMXD microchip assembly methods.
